/* define the function which converts the selected text in an instance,
and convert the string to upper or lower case. */
function convertCase(target, menuItem) {
var beginIndex:Number = Selection.getBeginIndex();
var endIndex:Number = Selection.getEndIndex();
var tempString:String;
// make sure that text is actually selected.
if (beginIndex>-1 && endIndex>-1) {
// set the temporary string to the text before the selected text.
tempString = target.text.slice(0, beginIndex);
switch (menuItem.caption) {
case 'Uppercase...' :
// if the user selects the "Uppercase..." context menu item, convert the
selected text to upper case.
tempString += target.text.substring(beginIndex,
endIndex).toUpperCase();
break;
case 'Lowercase...' :
tempString += target.text.substring(beginIndex,
endIndex).toLowerCase();
break;
}
// append the text after the selected text to the temporary string.
tempString += target.text.slice(endIndex);
// set the text in the target text field to the contents of the temporary
string.
target.text = tempString;
}
